Re: [Handle-info] indirect handles actually implemented?

Hi, to follow-up myself: I notice that the
HS_ALIAS *is* processed by both the browser
plugins and the hdl.handle.net web proxy:

Having a HS_ALIAS field with any arbitrary
index for a handle makes the system return
the data of the handle listed in the data
of the HS_ALIAS (eg "42/111")... In short,
the HS_ALIAS "blocks" access to any other
field/index of the "original" handle, and
lets you see contents  from the referred-
to handle for all your queries.

That is quite useful and somehow similar to
the indirect handles described in 1995, but
the "URL indirection" suggested in my other
mail is still useful in other scenarios. It
would be nice if the web proxy could do it.

Regards, Eric
